sPEcInrcAirIoN forming part of Letters Patent No, 781,426, dated January 31, 1905.

Y' Application filed October l., 1904. Serial No. 226,731.

Be it known that I, EDWARD HOLLING- WORTH, a subject of King Edward the VII of England, residing at Dobcross, in the county of York, England, have invented certain new and useful Improvements in Bearings for Cranks or other Shafts, of which the following is a specification.

This invention has reference to bearings for shafts or certainl shafts employed in looms and other machines; and the object of my invention is to provide a solid bearing andbush so constructed and arranged that the latter can be accurately and rigidlysecured to and in the bearing and disconnected at will to admit of the bush and shaft being raised. up clear of the bearing in the framework and removed without disturbing any gears or other parts fast on the shaft, this being of considerable advantage in what may be called a "solid bearing. In many of the bearings as at present constructed the shaft can only be removed by drawing itlongitudinally through the bearing after the gears and other parts have been removed. f

In my improved' construction of bearingv I am also enabled to minimize labor and time occupied in fitting the bearings,the parts iitting truly and accurately together.

Referring to the drawings, Figure 1 is an elevation of bearing and'bush for supporting a driven shaft 'embodying my improvements,

the bush being shown secured in proper position. Fig. 2 is a plan viewrof Fig. l. Fig.

3 is a similar elevation to Fig. 1, showingthe parts in the position occupied when inserting or withdrawing same from the bearing. In the accompanying drawings, letter a designates the bearing which is boredjin the framework or bracket b, an opening, as c, of less Widt'h than the diameter of the bearing, being left at the top or upper end of the bearing.

al is the bush, which is turned to fit truly'in the bearing u. The bushd has two opposite sides providedwith flat portions or'surfaces e e, which reduce the external diameter of the the bearing c.

' l bush-ione way-that is, from one flat portion e through the bush to the other flat portion eto substantially the same wid th as the opening c at the top of the bearing, so that when turned .partly round to present the fiat portions c at each side thereof, as illustrated in Fig. 3, the

bush OZ, with the shaft f, can be moved freely in a vertical direction into or Withdrawn from Inl Fig. 3 the bush d is shown in full lines in position for withdrawal from the bearing or as having just been placed into same and in dotted line partially out of the bearing,` as when inserting or withdrawing it therefrom. In the position shown at Fig. 3

the bush and shaft f are movable vertically out ofthe bearing without disturbing any gears or other parts mounted on the shaft. WhenV inserted into the bearing a, the bush Z is given a partial turn to bring the flat Vportions e e thereon to a horizontal position or at top and bottom of the bush, as shown at Fig.

V1, the rounded portions of the bush engaging or fitting nicely within the bearing a and locking the bush in position. n

- On the outer end of the bush Z are flanges or side extensions g g, suitably faced to lit accurately and truly against the planed face surrounding the bearing, said iianges or extensions having holes bored therethrough and admit of bolts It /L being passed through such openings in the framework and into the lianges or extensions and secured by nutsc' t', whereby the'bush is rigidly held in the bearing and a practically solid bearing obtained.

Having thus described. my invention, what I claim as new, and desire to secure by Letters Patent, is-

- 1. The combination with a frame or supporting -bracket, having a bearing -socket formed therein, with an opening of less width than the diameter of said socket, of a bush in which a shaft is adapted to be journaled, said bush having fiat portions 0n opposite sides which when the bush is engaged in the bear` 'ing' coincide with holes 1n the framework thereof to reduce its diameter, and adapt it to be inserted into, or withdrawn from said socket, and having a flange or flanges thereon, and means for securing the bush in position, substantially as shown and described.

2. A supporting frame or bracket having a bearing-socket formed therein, with an opening of less width than the diameter of said socket, and a bush to lit said socket, having flat portions on opposite sides thereof, to reduce the diameter of said bush, and adapt it to be inserted into, or Withdrawn from said IO socket, and said bush having thereon a lateral llange or langes, provided with holes adapted to receive bolts to secure the bush rigidly in position,substantially as shown and described.
